The beta_labs_campaign.zip file you have requested: Maps / First Maps / The Beta Labs Campaign - 2.47mb is not available. Perhaps try browsing all files for the game Doom III and upload any files you want to share or are missing. This is the only information we could locate:
The beta Labs Campaign is basicly the beta labs1, 2, and 3 put together into one file (a campaign) now to encourage you to download it (those of you who already have the three map) i went back and added new stuff to it so they will be new.I plan to make a series of maps to follow up the campaign (it will be like a T.V. series).
